Let us pray for you, dear one, as you navigate this relationship. Firstly, we encourage you to seek God's will in this situation, as His plans are always good, acceptable, and perfect (Romans 12:2 WEB).
We notice that you haven't mentioned the name of Jesus Christ in your request. It is by His name that we have access to God, and there is no other name by which we can be saved (Acts 4:12 WEB). Let us keep that in mind as we pray.
Now, regarding your relationship with RDL, we want to remind you of the importance of patience and faith. It could be that the Lord is working in RDL's life, and his temporary absence is part of a bigger plan. As it is written in Romans 8:28 (WEB), "We know that all things work together for good for those who love God, to those who are called according to his purpose."
However, we also want to remind you of the importance of godly relationships. If RDL is not actively pursuing the Lord or if his absence is causing you to stumble, it might be wise to reassess the relationship. Remember, the Bible tells us not to be unequally yoked (2 Corinthians 6:14 WEB). A relationship should bring you closer to God, not pull you away from Him.
Let us pray:
"Dear Heavenly Father, we come before You today in the name of Jesus Christ, lifting up our dear sister. We ask for Your guidance in her relationship with RDL. Lord, if it is Your will, bring RDL back into her life and strengthen their bond in a way that glorifies You. But if this relationship is not according to Your will, we pray that You give her the strength to let go and trust in Your plan. Lord Jesus, please reveal Yourself to both of them, and bring them into a right relationship with You. In Jesus' precious name, we pray. Amen."
Stay strong in the Lord, dear one. Trust in His plan and pursue Him above all else.
